    Command:

    stdbuf

    
    
    
    

    SYNOPSIS

           stdbuf OPTION... COMMAND
    
    
    

    DESCRIPTION

           Run COMMAND,  with  modified  buffering  operations  for  its  standard
           streams.
    
           Mandatory  arguments  to  long  options are mandatory for short options
           too.
    
           -i, --input=MODE
                  Adjust standard input stream buffering
    
           -o, --output=MODE
                  Adjust standard output stream buffering
    
           -e, --error=MODE
                  Adjust standard error stream buffering
    
           --help display this help and exit
    
           --version
                  output version information and exit
    
           If MODE is 'L' the corresponding stream will be  line  buffered.   This
           option is invalid with standard input.
    
           If MODE is '0' the corresponding stream will be unbuffered.
    
           Otherwise  MODE is a number which may be followed by one of the follow-
           ing: KB 1000, K 1024, MB 1000*1000, M 1024*1024, and so on for G, T, P,
           E,  Z, Y.  In this case the corresponding stream will be fully buffered
           with the buffer size set to MODE bytes.
    
           NOTE: If COMMAND adjusts the buffering of its standard  streams  ('tee'
           does  for  e.g.) then that will override corresponding settings changed
           by 'stdbuf'.  Also some filters (like 'dd' and 'cat'  etc.)  don't  use
           streams for I/O, and are thus unaffected by 'stdbuf' settings.
    
    
    

    EXAMPLES

           tail -f access.log | stdbuf -oL cut -d ' ' -f1 | uniq
           This will immedidately display unique entries from access.log
    
    
    

    BUGS

           On GLIBC platforms, specifying a buffer size, i.e. using fully buffered
           mode will result in undefined operation.

    REPORTING BUGS

           the command
    
                  info coreutils 'stdbuf invocation'
    
           should give you access to the complete manual.
